Best DSLR for £250

I've been asked to recommend the above for my niece who's 16. Can be 2nd hand.
She'll almost certainly want as many bells and whistles, shiney bits and acronyms as possible.
My interest in cameras stops at looking in the window of RG Lewis once every six months, so if y'all could give me some recommendations please.

Thoroughly recommend MPB, bought a Nikon D70 from them, and its been great. Met the owner of the site when I went to collect, and seemed a decent chap. You can get good lenses from there too, either start with a 50mm prime lense, great for portraits, general reportage type stuff, or 18-55mm zoom if you can afford it.
I rate Nikon, as very easy to use for beginners, but you cant go wrong with Canon either.
